Warranties are around 3-7 years with Vauxhall now 100,000 miles and no time limit to original buyer

Manufacturer's warranties are conditional upon servicing and repairs with "genuine original equipment manufacturer's part". Some warranties do also permit "parts of equal quality".

Insurers are adding clauses allowing them to repair with "parts not made by original manufacturer but of a similar standard/quality, including recycled parts". Others say just "parts not from original manufacturer including recycled parts". I can find no insurances saying "parts not from the original manufacturer provided of equal quality".

This seems to invalidate most manufacturer's warranties which means losing a valuable part of the purchase or having problems when claims arise.
